Xbox Group Post Exploit / Hack that leads to banned accounts.

Multiple users with new accounts are using a system or exploit to exploit the automatic ban feature built into Xbox. My account of 10 years, and many of my friends have had multiple false strikes put onto our accounts by random users who join our party. They message us clown emjois and say "Enjoy ur ban" This is ridiculous and I have no way to remove these unjust strikes or deal with the exploiters.

The group posts and messages are all available to view. Please someone help me with this issue, thank you.
